Here is a description from the Alphablocks website:
Alphablocks is a series of adventures that invite you and your child to have fun with words.
The Alphablocks are twenty-six living letters who fall out of the sky onto an empty, white world and discover that if they hold hands and make a word, it comes to life. They learn as they go along and they're always ready to have a go, help each other out and make their own entertainment.
Alphablocks is aimed at four-to-six-year-olds who are learning to read. Its simple purpose is to entertain, while showing that wordplay can be a lot of fun. It is based on best-practice phonics teaching and it can help young children develop engagement and confidence with reading and making words.
Every episode is different: there are songs, stories and games. The CBeebies Alphablocks website will feature all twenty-six episodes, with games that enable children to join in and make words to help the Alphablocks in their adventures.
